<snip> I see both OSS modules (ac97_codec, sound, emu10k1) and ALSA modules (snd, snd_pcm, snd_ac97_codec, etc.) loaded. They cannot both work. Read /usr/share/doc/alsa-base/NEWS.Debian.gz for details on disabling OSS modules for discover. > The appropriate audio devices appear to exist (and yes, I have run > MAKEDEV audio): > > aloysha:~# ls -l /dev/dsp > crw-rw---- 1 root audio 14, 3 Jun 22 00:21 /dev/dsp > > But, I hear no sound, and when I attempt the simple test of writing a > sound file to /dev/dsp (even as root, to avoid any permission issues), I > am told that the device doesn't exist! > > aloysha:/home/dcw/sndkit/dsp# cat endoftheworld > /dev/dsp > cat: write error: No such device My guess would be that the OSS modules grab /dev/dsp but they cannot grab the soundcard, since that one has already been taken by ALSA. However, I don't see a snd-pcm-oss module which emulates OSS and thus provides a /dev/dsp link. So, try to unload all OSS modules, load snd-pcm-oss and try catting to /dev/dsp again. I guess that should work... HTH, David -- Hi! I'm a .signature virus. Copy me into your ~/.signature to help me spread! -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
